Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

open access: yesBiological Reviews, EarlyView.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Element concentrations in tissues reveal spatial structure of Atlantic walrus management stocks

open access: yesThe Journal of Wildlife Management, EarlyView.
Differences in tissue element concentrations confirm geographic differentiation between 2 of Canada's walrus management stocks but reveal additional spatial structure within the largest stock that may have management implications. Abstract Ensuring harvested animal populations are managed at appropriate scales requires an understanding of underlying ...

Ground‐truthing of satellite imagery to assess seabird colony size: A test using Adélie penguins

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Adélie penguin colony size can be estimated from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery due to the contrast between their guano stain and the surrounding terrain. Our study assessed the utility of VHR imagery for making indirect assessments of changes in colony size.
